PRESSING ATTACHMENT FOR YARN-BEAMING Il/IACHINIES.l

Application led November 15, 1923. Serial Ne.'6?4,862.

To all whom t may concern: l

Be it known that I, JOHN C. BLAoKHURs'r, a subject of the King of Great Brit-ain, residing at Chorley, in the county of Lancashire, England, have invented new and useful Improvements in Pressing Attachments for Yarn-Beaming Machines, of which the following is a specification.

This invention is an improvement on the yarn-pressing means disclosed by lLetters Patent of the United States granted December 5, 1922, to Richard Anderton and myself, No. 1,487,703. Y

The `machine of said patent includes'a flanged beam, a longitudinally disposed drum rotated in connection with the beam, conical rollers bearing against the surface of the'beam in proximity to the flanges thereof, andadjustable bearings carrying said conical rollers, the object being to pro- 1 vide means whereby the yarn wound upon thev beam is pressed to approximately the` same extent close to the inner faces of the beam flanges as at other parts of the beam, thus obviating certain disadvantages formerly experienced.

The chief object of the present invention is to simplify and reduce the cost of the means for carrying the conical rollers and controlling the operation thereof.

Another object is to provide a pressing attachment, including said conicalv rollers, adapted to be installed as* a unit independently of the usual parts of the machine.

I `attain, the above-mentioned and other related objects by the construction hereinafter described and claimed.

Of the accompanying drawings forming a part of this specification,-

Figure 1 is aview, showing in section, aA

sufficient portion of a beaming machine, and in elevation a pressing attachment embodying my improvements.

levers 13, so as to rest on or be pressed into contact with the usual vdrum 14, the bearings allowing the beam to rise as its diameterl is increased by the winding of yarn thereon. The pressure between the yarn winding and the drum 14 causes the yarn to be 'tightly wound on the beam.

The machine includes'the usual levers 15, carrying a foot-board 16, said levers vand foot-board constituting the usual tr'eadle, controlling the usual clutch and belt shift device, in a manner wellunderst'ood inmachines of this character.

As `in the machine of the above-mentioned patent, I malte use of conical rollers 1T,

larger ends of the rollers rotating in Contact with, or in close proximity to the flanges 12a of the beam. The rollers exert pressure on the end portions of the winding, so that said portions are compacted, practically as closely as the intermediate portions of the winding.

In carrying out my invention I provide attachments, each including one of the conical rollers 17, said attachments being adapted to be installed independently of the machine and in such manner that the conical rollers may bear directly on the periphery ofthe beam 12, when the latter is empty, and may move outwardly from the beam as the winding of yarn'increases in diameter.

My improved attachment comprises a fixed standard 19, means for fixedly supporting the standard beside the drum 14, and adjacent to the outer side thereof, an oscillatory carrier 20, and a hinge connection between the upper end of the standard and the carrier, permitting movements of the carrier toward and from the beam, the conical roller 17 being mounted to rotate loosely on an arm or stud 21, fixed to the upper end of the carrier.

The standard 19 is preferably attachable to a floor 22, independently of the machine, although, if desired, its lower end may be secured directly to a suitable portion of the machine frame.

The standard is formed to project through the space' between the treadle foot-board 16 and the outer side of the drum, said footboard being in all cases spaced outward from the drum, as shown by Figure 1. In this instance, the standard is provided with a base 23, adapted to be independently se- Lil) cured, as by bolts 24, to the floor. The standard is inclined above the base and its arn rangement is such that it doesV not interfere with either' the drum 14C or'the treadle.

The hinge connection between the standard 19 and the carrier 20, is preferably embodied in a pair of upstanding ears24- and 25, iixed to the upper end of the standard, and a' hub portion 26 forming a part of the carrier, interposed between said ears and connected therewith'by a pintle 27.

The carrier includes two arms, one projecting upward and the other downward from the hub 26. The lower arm is -provided with spring-engaging means, preferably ,embodied in oppositely lprojecting ears 28, adapted to engage the upper ends of helical springs 29, the lower ends of which are engaged with anchoring means, such as hooks 30, fixed to the base 23. 1

Thesprings 29 act on the carrier to yieldingly press the conical roller 17 toward the beam.

' I provide one-way clutch parts, carried by the standard and the carrier and adapted to permit anoutward movement, and

Said clutch parts are preferably embodied' "y in ratchet teeth 31, formed on the ear 24, and

a pawl 32 pivoted to the upper arm of the carrier 20, and adapted to engage either of the teeth 31, the pawl being preferably provided with a handle 33, whereby it maybe disengaged from the ratchet teeth.

It will be seen by reference to Figure 5,

that the'attachment may be' entirely self-` eontained, the springs 29 being secured to' the carrier and to the base of the standard, so that all that is necessary to install the attachment, is to pass the standard through the spacefbetween the treadle foot-board and the drum, and bolt the. standard base to the floor, although, as above stated, the standard may be secured in any suitable way to a part f lof the frame of the machine. ,c

It is obvious that two of the described attachments will be provided Vfor each machine, the conical roller of one attachment bearing on one end and the conical roller et the other attachment bearing on the opposite end of the drum, or the yarn winding thereon.

The conical roller may be moved outward by.' hand from a completed winding on the beam, and retained by the one-way clutch Pre* vent an inwardV movement of the roller 17,

flanged beam adapted to be rotated by the drum' and movable from the drum by a Ywinding of yarn on the beam; a pressing attachment 'comprising a' standard, having means at its lower end whereby it may be lixedly secured tol'a support below the beam and adjacent to the outer side of the drum, an oscillatory carrier, a hinge connection between the upper end ofthe standardandv the carrier, permitting inward'and outward movements ofthejrarrler toward and from 'the' beam; a conical roller mountedl to rocarried by-v the standard and thecarrier andV adapted, to permit an outward movement and'prevent an inward movement ofthe roller relative tothe beam, the arrangement being such that the roller is adapted to bear on the outer side of the beam'when the latter isV ei'npty, and to be movedv forward and outward from'the beam not only by a winding of yarn thereon, but also manually p.

't-o separate it from said winding.

2. For use with 'a machine fonbeaming yarns, which includes ra rotaryV drum; al flanged beam adapted to be rotated" by the drum and movable from the drum by ka 1 winding of yarn on the beam, and a Clutch.' y operating treadle projecting forward from the drum, the foot piece of the treadle being separated by a space from the drum, a pressing` attachment comprising a standard formed to extend through said space without interference with the treadle, means for -fixedly supporting the standard, an'oscillatory carrier, a` hinge connection between the upper end 'of the standard, and the carrier, permitting movements of the carrier toward andfrom the beam; a conical roller mounted to rotate` loosely onthe upper end of the carrier, and adapted to bear on 'an end portion of a winding of yarn on the beam, springmeans "acting onthe carrier Vto yieldingly press the roller toward theV beam,

and one-wayrlutch parts carried by tlie` standard and the carrier, and adapted to permit.V an Voutward movement and prevent an inward movement of the roller relative to the beam,`the arrangement being such that the roller is adapted to bear on the beamvwhenV the latter is empty, and to be moved outward from the beam by a windingV of yarn thereon.

A'pressing attachment substantially as speciiiedbyclaim 1,'the said standard beingadapted to be fixedto a floor, and supported by the latter.independently of the vmachine' 'and the said spring means beingconnected witlr said carrier and the standard, so thatA the attachment-is self-containedf1. f-

one of said ears having ratchet teeth7 a hub forming a part of' said carrier and interposed between said ears, and a pintie eonnecting' the hub with the ears, the Carrier includingl an upper arm carrying a paw! adapted to engage either of said teeth and a lower arm having spring-engaging means.

In testimoni7 whereof I have aixed my signature.
